The 'Rehab' singer - who had been banned from entering the country two years ago after being arrested for possession of cannabis and was also denied a work visa months later after being accused of assaulting a fan - is keen to tour America now authorities have relented on their previous decisions.

A source said: "Amy loves the idea of jetting off to America. She really wants to go to the States and play some shows.

"She knows she has a huge fan base there and would love to boost her profile further and give something back to all the people who buy her records."

Last month, Amy - who won five Grammy Awards in 2008 but had to accept her prizes and perform via video link in the UK because she was refused entry by US authorities - was cleared of the assault which stopped her from getting a work visa two years.

Her spokesperson said: "There is nothing to stop her getting a visa to travel to America. 'Back to Black' was the second biggest-selling album in the world last year and she never had the chance to tour there, so it's on the cards."

The 25-year-old singer recently returned to the UK after an extended break in St. Lucia, where she had been working on her third album away from the distractions of the London party scene.
